Product Details iK41

iK41 combines four Class D amplifier channels, loudspeaker DSP and network control in a 2U rack chassis. Its applications include WPM line arrays, TORUS 8 and selected other Martin Audio loudspeakers. The integrated platform is designed to provide both the amplifier power and processing required by the supported loudspeaker system.

Published output is 1500 W per channel into 4 ohms, with up to 6000 W total under the stated load conditions. The efficient Class D design reduces mains demand while maintaining the power reserve needed for demanding live programmes.

Ethernet connects the amplifier to VU-NET for remote control and monitoring. A front-panel interface also provides local control. Analogue, AES3 and Dante digital inputs are available, with AES67 compatibility on the network-audio input.

The integrated DSP supports the relevant loudspeaker presets and DISPLAY optimisation for WPM. Up to 1000 FIR taps at 48 kHz are available on each output. Normal DSP operation is at 96 kHz, with output processing at 48 kHz when FIR filtering is implemented.

Peak, RMS and excursion limiting protect the loudspeaker, with multiband limiting for passive two-way systems. Amplifier monitoring and protection maintain the operating conditions of the complete system. The switch-mode supply auto-senses the specified 85–240 V mains range.
